Dry Back Paint Booth
Autocoat has designed & developed new series of Dry Back Paint Booth with amazingly low running cost of replacement of filters as well as to meet Pollution norms.
Costly replacement of filters is a big hurdle in Indian industries & management do not like costly filter purchase every month & lot of competitors paint booth lies idle or forced to use with poor performance.
The DRY BACK SPRAY PAINT BOOTH is also called as Low Cost Spray Booth since they are cheaper than compared with Water Type Paint Booth.
These kinds of booths are more popular in painting application with low paint consumption (around 20 ltrs/shift) as well as in laboratory and research and development. As mentioned above Autocoat designed DRY BACK SPRAY BOOTHS are designed with cleanable & removable type metal baffles which arrest most of the paint overspray, thus leaving behind clear and less smoky air towards the exhauster.
The main advantage in the Metallic Baffled Dry Back Paint Booth is that it can be cleaned by usual cleaning methods and reused as before and also reduces the maintenance cost & reduces filter replacement cost amazingly.
The main disadvantage in the coarse filter Dry Back Paint Booth (by competitors) is that filters cannot be cleaned by usual cleaning methods and reused as before since the filters are to replaced as soon as they are chocked with paint particulate after which no air can passed through & thus heavy filter replacement cost.

Unlike Autocoat Dry Back Paint Booth competitors paint booth are often provided with designed with paint filters which chocks more frequently (for chocking of filters can be 1-2 week if paint consumption 20 ltrs. Per/Shift) and must be replaced to get same performance in the paint booth & if not replace then painter will be uncomfortable & resist carrying on painting Production loss

FAQ
Frequently Asked Questions
What is a dry back paint booth?
A dry back paint booth is a spray booth that captures overspray using dry paper, fibreglass, or pleated filter pads rather than a water curtain. The "dry back" refers to the back wall of the booth where filtered exhaust air passes through arrestor media before leaving via the blower and stack.
How does dry filtration work in a paint booth?
Dry filtration uses multi-layer pads that progressively trap paint particles — coarse glass-fibre catches large droplets, while denser fibreboard or accordion paper captures fine mist. As paint loads up the media, pressure drop increases until replacement is needed. The media must match paint type, viscosity, and overspray volume.
When should I choose a dry back booth over water wash?
Choose a dry back booth when your daily painting volume is moderate, your facility has limited water supply or drainage, you need lower civil work, or you spray water-based and powder-compatible paints. Water-wash booths suit very high-volume continuous-line painting where filter replacement frequency would be impractical for dry systems.
What kind of filter media does a dry back booth use?
Dry back booths use cardboard accordion paint arrestors, multi-ply fibreglass overspray pads, paper-fibre composite layers, or pleated synthetic media depending on paint type. Coarse pre-filters often back finer pleated panels for two-stage capture. Autocoat recommends specific media grade for solvent, water-based, or two-pack PU paints during specification.
How long do dry back booth filters last?
Dry back filter life depends on paint volume — typically 2-4 weeks of single-shift operation for high-overspray solvent paints, 6-8 weeks for low-volume work, and longer for waterborne. The manometer pressure-drop reading is the most accurate indicator. Autocoat supplies replacement media in standard and custom sizes for any dry back booth brand.
Are dry back booths suitable for high-volume painting?
Dry back booths handle moderate to high painting volumes well — typically up to two-shift continuous operation. For very high paint-volume continuous lines (large auto OEM body shops), water-wash designs may be more economical because they don't need frequent media changes. Autocoat advises the better choice during requirement analysis.
Is a dry back booth easier to maintain?
Yes. Dry back booths are simpler to maintain than water-wash because there's no chemical dosing, no water tank, no sludge skimmer, and no pH balancing. Maintenance comes down to filter inspection, replacement, and cleaning the booth interior. This makes dry back the preferred choice for SMEs without dedicated maintenance staff.
What is the airflow design of a dry back paint booth?
Dry back booths use cross-flow or down-flow designs. Air enters from ceiling filters, passes the operator and component, then exhausts through dry arrestor pads on the rear wall. Airflow velocity is typically 0.3-0.5 m/s in the working zone. Balanced intake and exhaust pressure ensures consistent capture and a clean finish.
What is the cost of a dry back paint booth?
The cost of a dry back paint booth varies depending on size, type, and automation. Key factors include enclosure dimensions, airflow rate, filter media grade, lighting, blower power, heating option, and customisation for component shape.

Does Autocoat customise dry back booths for specific industries?
Yes. Autocoat designs dry back booths customised for furniture, FRP, valve, motor, alternator, fitness equipment, electrical panel, and aerospace component painting. Customisation covers booth size, hook fixtures, airflow direction, filter grade, lighting type, and bake-cycle integration.
